In accordance, preliminary data obtained with primary human breast tumor tissue cDNA array (BCRT101; Origene Technologies, Rockville, MD, USA) displayed relatively higher expression of StAR mRNA in ER+/PR+ BCs, when compared with either TNBC or normal mammary epithelial tissue (Manna, PR, unpublished observation). The gene discussed is PGR; the disease is breast neoplasm.
